While technology adoption is non-randomly assigned to farmers, we draw on recent advances of machine learning models to identify farm adoption profiles of multiple agricultural technologies. Combining the stochastic production frontier with the inverse probability weights, we compare the TE between adopters and non-adopters. Although, farmers adopting new seed varieties achieve significantly higher TE than others, dissemination of integrated pest management practices by extension agents affect negatively farm performance. Results show that there is a positive relationship between actions to reduce the vulnerability of landscapes to soil erosion and corn productivity. We find heterogeneous effects of adopting multiple environmentally friendly technologies on TE. Farmers who are a member of cooperative and employ organic fertilizer are associated with higher odds to adopt new seed varieties. Maize cultivation in sloping land and farmers with large landholdings tend to be the key drivers in the provision of farm advisory services and the exertion of soil erosion control techniques. Sensitivity analysis suggests that the empirical findings are largely robust against the hidden hazard of unmeasured confounders.","PeriodicalId":429425,"journal":{"name":"AARN: Agriculture (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117003159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology employed in the review involves searching keywords related to the study objectives on relevant literature search engines and platforms, including Google Scholar and Cross Referencing through triangulation of search results. The articles were screened and validated for inclusion or exclusion based on relevance, content and context. The review process follows the sustainable livelihoods framework. The search returns are complimented with published reports. The report provides information on the current status and guidance on appropriate interventions and innovative investments in Nigeria. Specifically, this report provides a systematic literature review on: 1) situation and trends in energy and land use changes, 2) observed and projected impacts of climate change, 3) technological, socioeconomic and policy actions for sustainable land management and climate change adaptation and mitigation, 4) evaluation of existing major policies and investments, and 5) conclusion and policy implications. \u0000 \u0000Based on the assessment of literature in this study, the key trends and problems include inadequate attention to the agricultural sector over the years, which has caused a major setback in food security and productivity. Climate change has further exacerbated the problem through desertification, drought and flooding across the country. The literature further revealed inadequate energy supply, distribution and low per capita consumption in Nigeria. The use of fuel wood for heating and cooking has significantly contributed to deforestation by worsening land degradation. Resulting implications are that food security is threatened and economic growth is hampered. Land degradation negatively impacts the environment and the rural poor whose livelihoods depend on it. Opportunities in agriculture and renewable energy should be further harnessed and forest and land use policies should be enforced to ensure sustainable livelihoods. In Nigeria, policies and investment plans on land use, energy/electricity and agricultural livelihoods are not coherent and lack consistency in implementation. Thus, lack of strong institutions has resulted in the weak performance witnessed in programme and policy implementation on climate change mitigation, land use, energy and sustainable development in Nigeria. Therefore, there is a need for productive, viable, sustainable policy and programmes that support climate change mitigation, land use, energy and sustainable development in Nigeria. Another important suggestion is the need for provision of renewable energy mix (off-grid) in forms that are easily accessible and affordable by households. Adequate attention should be paid to the provision of bio-energy and the wider bio-economy framework, including the transformation of solid waste, wood waste and agricultural was","PeriodicalId":429425,"journal":{"name":"AARN: Agriculture (Topic)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122652753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this investigation was to identify the determinant factors of farmers’ participation in the Nigeria’s growth enhancement support scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. One thousand, two hundred rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub-Saharan Africa can be achieved by increasing the participation of rural farmers in the growth enhancement support scheme.","PeriodicalId":429425,"journal":{"name":"AARN: Agriculture (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115338312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excessive supply of vegetables reduces the market price that leads to economic loss at farm level. This study  assesses the growth and trend of winter vegetables production, yield and area in Bangladesh. Semi-log regression model was used to assess the growth and trend of winter vegetables while Winston Prais transformation was utilized to solve the autocorrelation problem. Yearly time series data of collected from secondary sources was used for this analysis. Data were collected from 1986–87 to 2015–16 years. Data of some major winter vegetables like tomato, rabi brinjal, rabi pumpkin, water gourd, cauliflower, cabbage, radish, bean, green spinach were collected for this study. Results found that growth of tomato, cauliflower and cabbage production was about 5% which was much higher than other winter vegetables. Growth of cultivated area is about 3% per annum for most of the vegetables. Production of winter vegetables increases because of yield and area growth. Government can attempt to increase export of tomato, cauliflower and cabbage. Moreover, yield growth of green spinach and radish is necessary to increase both production and export. \u0000J.

India showed tremendous growth in potato production during last one and half decade, however, this growth is led more by the area expansion than the yield enhancement. For further analysis on nature of productivity growth in Indian potato sector the computation of Total Factor Productivity (TFP) was done with the help of Malmquist Productivity Index (MPI). Year 2005 being the inflection point in the growth in Indian agriculture was used as period break year for this study and two periods, viz. pre-period (1997 to 2004) and post period (2005 to 2013) were considered for all analysis and descriptions. Bihar, West Bengal and Uttar Pradesh states constitute about 74% of Indian potato production hence, these states were assumed to represent Indian potato scenario. Except mild decline in potato productivity growth in Uttar Pradesh, area, production and productivity growth of potato showed acceleration in post-period compared to the pre-period in all the states. TFP improved in all the three states in post period however, in West Bengal the growth was negative (-2.3) even in the post period. Except Bihar where efficiency change was positive (1%) in pre-period, and further improved in post-period (2.1%), the efficiency change stagnated in all other cases.
